A Tomball man was arrested for solicitation of a minor after a routine traffic stop found him with a teenage girl he met online, according to the Tomball Police Department.

Robert Tyler Patrick, 31, was stopped by Tomball police early Saturday for having an expired registration sticker on his vehicle. In a prepared statement, Tomball police said that they noticed inside the vehicle a number of large bags and a suitcase all belonging to the minor, who resides in Houston.

Police said the girl, 16, told them that the pair met through the online chat app Whisper and that he was taking her to his Tomball apartment. Patrick told police, the statement said, that he was in the process of taking her to family members in San Antonio after she said she had been kicked out of her house by a parent.

Tomball police said they contacted the girl's family, who said that they had no idea who Patrick was and that they believed she was spending the night at a friend's house.

Police said Patrick later told investigators that he and the girl started what he called an inappropriate relationship online and that they had traded explicit photos between each other. Patrick and the teen's cellphones and computers were seized by police for forensic analysis.

According to court documents, the 31-year-old had misrepresented himself as being 17 years old while chatting online with the teen.

Patrick is free on $10,000 bond and his next court date is April 24, according to Harris County court documents.
